Key Features
The Monitor Audio C1S is designed for cost-effective in-ceiling installations where space is limited but clear, discreet audio is still needed. Its two-way design combines a 5-inch C-CAM mid-bass driver with a 1-inch C-CAM tweeter, making it a practical choice for background music, TV audio, and smaller room systems.
With a 40Hz to 30kHz installed frequency response, 84dB sensitivity, and 50W continuous power handling, the C1S offers a simple entry point into Monitor Audio’s Creator Series. The UD Waveguide helps spread high frequencies more evenly into the room, while the compact 171mm cut-out makes it easier to position than the larger C1M and C1L models. It is supplied with a white round grille for a clean ceiling finish.

The S in C1S refers to its small format within Monitor Audio’s Creator Series in-ceiling range, making it the most compact Tier 1 option. Compared with the C1M and C1L, it uses a smaller 5-inch C-CAM mid-bass driver and a 171mm cut-out, so it is easier to place in tighter ceiling areas. This makes it well suited to hallways, kitchens, bedrooms, studies and multi-room systems where discreet coverage, simple placement and clean everyday sound matter more than maximum output from a neatly hidden speaker above the room.
Quik-Link speaker cable connection helps make wiring faster and tidier, which is useful when fitting several speakers across a home. It reduces cable handling above the ceiling and supports a cleaner installation process for everyday audio projects. Tri-Grip II then secures the C1S firmly into the ceiling, giving installers a reliable fit once the speaker is positioned. With a 99mm mounting depth and supplied white round grille, it offers straightforward planning before fitting begins and a neat final finish that blends easily into most rooms.
